The Bozi Breakdown Episode 3: Talking Aero with Joey Cohen
Joey Cohen joins the Bozi Breakdown in Episode 3 to dissect the recent Texas NASCAR race. They highlight the track's unique challenge with two distinct ends requiring compromises. They focus on the Next Gen car's "aero attitude" with underbody downforce via the rear diffuser. Joey explains the difficulty of planning for races with 35 other cars, as the car's aero sensitivity in traffic significantly differs from single-car testing.
